Patent CA-1048791-A (CA)
Inventor: DEGELMAN WILFRED J
IPC: A01B43/00
Filed: 1976-06-15
Granted: 1979-02-20
Abstract: Abstract of the Disclosure A rock windrower of the rotating helix type is provided with a castored teeth-supporting drum which is spring-loaded to permit a floating engagement of the drum with the surface of the ground.  When heavy rocks or other obstacles too large to be conveniently moved by the windrower are en-countered by the lowermost teeth of the counter-rotating drum, the drum simply rises over the obstacles, relieving tension on the spring and thus permitting the drum, under its own weight, to return into ground surface engagement once the obstacle has been cleared.  A hydraulic piston and cylinder arrangement permits adjustment of the drum position above the earth's surface.  The horizontal angle of inclin-ation of the drum relative to the direction of motion is adjustable, the exit end of the drum preferably lying somewhat to the rear of the other end of the drum.  The frame is pre-ferably triangular with the hitch located at the forward apex of the triangle and the frame supporting the wheels located at or near the two rear apexes of the triangle im-mediately behind the drum.  The horizontal angle of inclination of the drum is adjustable within a small angular range.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention concerns toy animal figures with four legs and a rigid, shaped body.  In order to achieve as natural an appearance of such figures as possible, also to enable a toy human figure with a realistically small leg spacing to be mounted on the animal figure, preferably with a saddle, the middle of the animal body is formed by a narrow web coverable either by a centrepiece completing the body or by a saddle. When the centrepiece is placed in position no "rider" can be mounted thereon.  When, however, a saddle is mounted, in place of the centrepiece, a figure with small leg spacing can "ride" on the animal.

Abstract: A B S T R A C T     In a process for the production of aluminium a molten alumina slag, containing combined carbon is circulated through one or more alternately arranged relatively low temperature zones where carbon is added to increase the combined carbon content of the slag by reaction with the alumina slag and high temperature zones where aluminium metal is released by reaction of aluminium carbide and alumina in the slag with consequent depletion of the combined carbon content.          Alumina is supplied to the slag at one or more locations.   The energy to drive the reactions is preferably supplied by resistance heating of the slag particularly in transit from a low temperature zone to a high temperature zone although usually additional energy is supplied to the slag in the return from a high temperature zone to the next low temperature zone.         In most instances the aluminium-liberating reaction is carried out in an upwardly inclined passage and the gas evolved is employed to achieve the circulatory movement of the slag.          It is a preferred feature to scrub the gas with carbon without admixed alumina to avoid formation of sticky aluminium oxycarbide in the carbon, which is subsequently added as process charge.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a low noise amplifier capable of handling large signals without significant distortion and which is particularly useful as the first electronic stage in hydrophone array systems utilizing piezoelectric sensor elements.  The amplifier comprises three stages.  The first stage uses an input field effect transistor (FET), which is protected against overload by very low leakage current diodes, and which acts as a voltage-to-current converter.  The second stage comprises a junction transistor connected in a common emitter configuration which acts as a current-to-voltage converter. The third stage is a further junction transistor connected as an emitter follower.  The overall gain of the amplifier is controlled by a feedback connection from the third stage to the first stage.  The second and third stages are powered by a bipolar power supply.  The second stage junction transistor has its emitter connected to the positive supply voltage by a pair of diodes forward biased by the supply voltage to provide low distortion and fast overload recovery.  The third stage includes a second field effect transistor (FET), in series with the junction transistor of the third stage, which allows enhanced output drive capability.  Resistors are connected in series with the base and collector of the third stage junction transistor to provide output short circuit protection.
